Usage Note

As large structures (containing >62 chains and/or 99999 ATOM lines) cannot be represented in the legacy PDB file format, data are available in the PDB archive as:

Single PDBx/mmCIF files that represent the entire structure. The single PDBx/mmCIF files are available from each Structure Summary page on the RCSB PDB website and from the FTP archive (in directories of the format ftp://ftp.wwpdb.org/pub/pdb/data/structures/divided/mmCIF/bc/abcd.cif.gz).

TAR files containing a collection of best effort/minimal files in the PDB file format to support users and software tools that rely solely on the PDB file format. The entire structure is divided into several minimal files. The TAR files are available for download from each Structure Summary page and in a separate directory in the PDB FTP archive
(ftp://ftp.wwpdb.org/pub/pdb/compatible/pdb_bundle/)
grouped by the middle two characters of the 4-character PDB ID.

An index of all large structure entries (that do not have a standard PDB format file) is updated regularly on the PDB FTP site at
ftp://ftp.wwpdb.org/pub/pdb/compatible/pdb_bundle/pdb_bundle_index.txt. This list will continue to grow as new large structures are deposited and released. These entries can also be selected using Advanced Search (under Structure Annotation > Large Structures)
